I think this issue is related to protobuf, which uses C++ 11 features.

EmpireofKings · 2018-05-03T20:52:32Z

Hello my friend. what did you do to get this to work ? i have encountered the same issue, any help would be much appreciated.

yeshengm · 2018-05-05T05:35:00Z

@EmpireofKings Generally there are two options: 1. use up-to-date protobuf, and add -std=c++11 to CXXFAGS in makefile, which could be a bit painful; 2. use protobuf 2.x, which is c++ 98 compatible.

shallyxxxx · 2018-05-15T02:39:33Z

I meet the same problem. Have you fixed it?@yaxinshen

MINZHIJI · 2018-06-13T10:37:52Z

@shallyxxxx
I solved this problem by modifying CMakeList.txt
Orginal

# ---[ Flags
if(UNIX OR APPLE)
  set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fPIC -Wall")
endif()if()

Modify

# ---[ Flags
if(UNIX OR APPLE)
  set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fPIC -Wall -std=c++11")
endif()if()

amitfishy · 2018-06-13T11:40:18Z

@manifoldQAQ
Thanks this worked for me. I also had to add it to the NVCCFLAGS in the makefile for it to build the NVCC portion successfully.
And also to LINKFLAGS for using make test.

CXXFLAGS += -pthread -fPIC $(COMMON_FLAGS) $(WARNINGS) -std=c++11
NVCCFLAGS += -D_FORCE_INLINES -ccbin=$(CXX) -Xcompiler -fPIC $(COMMON_FLAGS) -std=c++11
LINKFLAGS += -pthread -fPIC $(COMMON_FLAGS) $(WARNINGS) -std=c++11

ujsyehao · 2018-06-29T03:46:29Z

@manifoldQAQ Good job!

ujsyehao · 2018-06-29T08:02:30Z

@amitfishy Hi, I follow your advice, and remove *.pb, then make it, it works well.
However, when I run ./build/tools/caffe train, it has the error:

How to solve the problem? I find some information about 'this program require a version of protobuf' # 5711, most solutions are to rollback protoc version to 2.6, but we need protoc version3.6, So how to make caffe support protobuf 3.6?

amitfishy · 2018-06-29T08:21:03Z

Firstly I followed the standard procedure for building caffe. Also I don't recall saying anything about the .pb files here.

I never came across this error specifically but came across similar things.
First take a look at the protoc version by:

protoc --version

You should see 2.6.1 which is your current protobuf version which you must have installed with apt-get.

You must be using cuda 9 which I believe needs v3.6, you can try installing the google protobuf by source. Following the install instructions will install in the default place which should be different from where your apt-get libraries are stored. Be careful if you try to remove the old libs or upgrade them, they can cause issues while booting.

Once you install by source, make sure it is being picked up correctly by checking with the version command or edit the order of the path variables as I've mentioned above in #3046 .

ujsyehao · 2018-06-29T08:26:59Z

@amitfishy I have installed protoc version3.6

ujsyehao · 2018-06-29T08:36:12Z

So I am confused,
When protocol version is 3.6, re-make caffe will cause the error:
"#error This file requires compiler and library support for the ISO C++ 2011 standard."
So I add -std=c++ 11 in makefile and it works well, this can explain caffe is using protoc 3.6.
when I run caffe, it says "this program requires version 3.6 of protocol, but the installed version is 2.6.1", why caffe report the error?

amitfishy · 2018-06-29T08:41:16Z

Find the .so and .a libs (probably in /usr/local/lib) for your v3.6 and add them to LD_LIBRARY_PATH and LIBRARY_PATH env variables respectively. Make sure to add them in the beginning like:

export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
echo $LD_LIBRARY_PATH //make sure /usr/local/lib is in start

Probably your makefile was pointing to those directories correctly and during runtime it's finding the other version.

ujsyehao · 2018-06-29T08:54:27Z

Thank you for your reply @amitfishy,
I have added them in LD_LIBRARY_PATH, but it doesn't work well, I guess your advice 'during runtime it's finding the other version' is right, how caffe find protoc during runtime?

amitfishy · 2018-06-29T08:58:03Z

Go explore your file system. Find libprotobuf.a and libprotobuf.so (one set will be 9 and the other will be 15)
For v3.5

For v2.6

amitfishy · 2018-06-29T09:12:17Z

Could you please try in the build folder:

ldd caffe | grep proto

And share the output?

ujsyehao · 2018-06-29T09:12:33Z

I don't understand.

ujsyehao · 2018-06-29T09:14:47Z

Follow your advice:

The caffe has two protobuf dll.

amitfishy · 2018-06-29T09:26:18Z

It might be picking up the first one(v2.5) instead of the second (v3.6).

Try the following if you're still up for it:

make clean
export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
export LIBRARY_PATH=/usr/local/lib:$LIBRARY_PATH
sudo ldconfig
make all
make test
make runtest

ujsyehao · 2018-06-29T09:28:32Z

Below is my another compiled caffe(protoc 2.6):

amitfishy · 2018-06-29T09:35:15Z

Try rebuilding it such that it gets linked with the right .so and .a libs. Don't forget the:

sudo ldconfig

After exporting the LD path.

ujsyehao · 2018-06-29T09:37:03Z

When I export LIBRARY_PATH, it has the error '/etc/profile: 30: bad assignment'.

ujsyehao · 2018-06-29T09:40:03Z

@amitfishy It works!
I am running 'make runtest'. I will post later.
hahaha

Thank you very much for your help @amitfishy !

amitfishy · 2018-06-29T09:45:19Z

Good to hear, the problem was the build was linked with the older libs, while the runtime libs were fine.

ujsyehao · 2018-06-29T09:52:42Z

In summary, the build was linked with older protoc version, I forget to make clean, and LIBRARY_PATH has no effect.
Now caffe can support protoc version 3.6!

amitfishy · 2018-06-29T09:55:44Z

Can you check what

ldd caffe | grep proto

gives you now?

ujsyehao · 2018-06-29T10:09:43Z

It gives the correct version.

BUT both did not worked for me
PLZ HELP ANYBODY

amitfishy · 2018-07-12T05:57:11Z

Check the g++ specified in your makefile.

Try:

man g++      //or put whichever g++ binary is being picked up (/usr/bin/g++)

Scroll down and look whether -std flag has option for c++11. If it doesn't, try changing the g++ compiler version. I'm using:

g++ --version
g++ (Ubuntu 5.4.0-6ubuntu1~16.04.9) 5.4.0 20160609

yeshengm · 2018-12-05T07:14:11Z

@soulslicer I guess Caffe is no longer actively maintained. You can either hack with Caffe source code or use Caffe2. If you don't want to use Caffe, then some dirty job has to be done to the Makefile in order to use Protobuf 3.x.

soulslicer · 2018-12-05T16:49:00Z

No you dont you just need to add that one word into the cmakelists.

"conda install protobuf = 3.2"
